ABSTRACT
Objective To discuss MSCT signs of colon multiple diverticulum in order to improve the accuracy of diagnosis.Meth-ods MSCT signs and clinical data of 30 cases with colon multiple diverticulum of were analyzed retrospectively.Imaging character-istics of colon multiple diverticulum were summarized and comparated with the results of colonoscopic appearance.Results There were 30 cases of colon multiple diverticulum confirmed by colonoscopy,including 1 6 cases in the ascending colon,6 cases the de-scending colon,5 cases the sigmoid colon,1 case transverse colon,2 cases the whole colon,5 cases with diverticulitis.Multiple pro-jecting processes were showed in 1 9 cases(63.3%,1 9/30),lesion diameter were 3.0-10.0 mm,gas or liquid filled in the lesion in 1 1 cases,small bezoar filled in 8 cases and the surrounding fat gaps were fuzzy in 5 cases.There was no any MSCT abnormal sign in 1 1 cases.Conclusion The typical MSCT signs of colon multiple diverticulum are multiple projecting processes,which size is smaller than 1 cm and filled with gas,liquid or small bezoar.The sign of surrounding fat gap fuzzy often means diverticulitis.
ABSTRACT
Objective To observe the effects of telmisartan treatment on the abdominal fat deposit in metabolic syndrome (MS) combined with essential hypertension (EH).Methods Sixty patients of MS combined with EH were divided into two groups according to random number table method,with 30 cases in each group.The patients in experimental group were given telmisartan orally 40 mg once a day,and in control group were given valsartan 80 mg once a day,until average ambulatory blood pressure monitoring blood pressure was ＜ 140/90 mmHg (1 mmHg =0.133 kPa) in 24 weeks.The visceral fat area (VFA) and subdermal fat area (SFA) was measured by multislice CT,at the same time the body mass index (BMI),blood pressure,blood glucose,homeostasis model assessment of insulin resistance (HOMA-IR) and glyeosylated hemoglobin (HbA1c) of the subjects was measured.Results The blood pressure,BMI,blood glucose,HbA1c,and blood lipids between two groups before treatment had no statistical significance (P ＞0.05).VFA in experimental group after treatment was lower than that before treatment [(127.8 ± 16.6) cm2 vs.(150.5 ± 15.4) cm2] (P ＜ 0.05).But there was no statistical significance of VAF in control group before and after treatment (P ＞0.05).The SFA in experimental group and control group had no statistical significance before and after the treatment (P ＞ 0.05).The HOMA-IR in experimental group after treatment was reduced compared with that before treatment (1.9 ± 0.3 vs.4.2 ± 0.9),and adiponectin was increased [(5.77 ±0.71) mg/L vs.(3.16 ±0.72) mg/L] (P ＜0.05).Conclusion Compared with valsartan,telmisartan can significantly reduce the visceral fat deposition in MS combined with EH patients and improve insulin resistance.
ABSTRACT
Objective To improve the accuracy of imaging diagnosis of intrathoracic tumor-simulating extramedullary hematopoiesis(EMH).Methods The chest radiographs and CT findings in two cases of intrathoracic tumor-simulating EMH with thalassemia were analyzed respectively and some related literatures were reviewed.Results A conventional chest X-ray showed rotundity or lobulated masses in the posterior inferior mediastinum in two cases, and CT scans showed smoothly marginated , homogeneous, lobulated paravertebral masses, on enhanced CT scans, the masses showed mild homogeneous enhancement.Conclusion Although intrathoracic tumor-simulating EMH is short of typical imaging features, the combination of clinical ,laboratory and radiological findings could make the diagnosis of intrathoracic tumor-simulating EMH, so unnecessary treatment or surgery could be avoided.
